Talent Trees: Both Operatives and Scoundrels have two melee dps talent trees with stealth abilities and one healing talent tree.

Resource: The main resource of Imperial Agents and Smugglers is energy. Energy regeneration is incremental and it depends on your current ammount of energy. In other words, the higher your energy level, the higher your regeneration will be (so a good strategy would be to focus on having decent/high levels of energy to benefit from good regen).

Unique Mechanic: Some damage abilities, direct heals and HoTs (healing over time) provide each one point of Tactical Advantage. Similarly, the abilities that consume Tactical Advantage, will only consume one point. Since almost all abilities that use Tactical Advantage do not consume Energy, using TA abilities is crucial to maintaining high levels of Energy and Energy regen.

Operatives and Scoundrels use HoTs more than other healing abilities, which easily allows them to keep players alive when the fight is not too demanding. Since HoTs give you TA points, this will help you rotate your direct heals (Kolto Infusion, Kolto Injection and Surgical Probe).

Talent Trees: Mercenaries and Commandos have two dps talent trees and one healing tree. They are basically casters in heavy armors.

Resource: Bounty Hunter’s main resource is Heat (capped at 100) while Trooper uses Ammo (capped at 12). They both work on same principles as Energy (including regen).

Unique Mechanic: Your free healing abilities and cast heals (when improved through talents) will stack Combat Support, a buff that boosts your healing. When you reach the max stack limit of 30, you can use it to add a temporary bonus effect of 10 seconds to your abilities by venting Heat/restoring Ammo..

Talent Trees: Sith Sorceror and Jedi Sage have two ranged dps talent trees and one for healing.

Resource: Sorcerors and Sages rely on Force as their main resource. Force regeneration is constant (8 Force/ second) and it’s capped (depending on talents) at 500/600. Because unlike the previous healers, Sorcerors and Sages have the constant regen rate and are able to consume it to lower levels, their heals are more expensive.

Unique Mechanic: Force Bending has a chance of being provided by Resurgence and boosts the effect of your next heal.
